* snow: remove an obsolete av_assert2Andreas Cadhalpun2015-07-101-2/+2
| | | | | | | | | | | | | | | | | | | | It asserts that the frame linesize is larger than 37, but it can be smaller and decoding such frames works. Before commit cc884a35 src_stride > 7*MB_SIZE was necessary, because the blocks were interleaved in the tmp buffer and the last block was added with an offset of 6*MB_SIZE. It was changed for src_stride <= 7*MB_SIZE to write the blocks sequentially, hence the larger tmp_step. After that the assert was only necessary to make sure that the buffer remained large enough. Since commit bd2b6b33 s->scratchbuf is used as tmp buffer. As part of commit 86e107a7 the minimal scratchbuf size was increased to 256*7*MB_SIZE, which is enough for any src_stride <= 7*MB_SIZE. Also add a comment explaining the tmp_step calculation. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

* | libavcodec: Implementation of AAC_fixed_decoder (LC-module) [4/4]Jovan Zelincevic2015-07-094-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Build system modified There are several warnings occurring during build after this patch is applied. The cause of most of these warnings is in that some definitions needed here are logical part of sbr module and are added in later patches. When this patches are applied these warnings stop occurring. The only warning that is added here and is not fixed with later patches is warning that warns that type mismatch for table ff_aac_eld_window_480. The reason for this warning is in that ER AAC ELD 480 is not integrated in to the fixed point implementation at this moment and there is no fixed point version of this table.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Freeze picture release should be set to 1 when we're responding to a fast update request. For simplicity we set it for all intra frames, including those that starts a GOP.
